Abstract

The format of the Presence Information Data Format-Location Object (PIDF-LO) as defined by the Internet Engineering Task Force (IETF) is extended or modified to accommodate, within the standard PIDF-LO format, an association of geospacial location to XML content on the Internet. A geospacial location is associated with Extensible Markup Language (XML) content on the Internet. The XML content is identified by a universal resource locator (URL), and associated with geospatial location information (either a specific location, zone, or direction). The URL is inserted into a <presence . . . > section of a Presence Information Data Format-Location Object (PIDF-LO) compliant document as defined by the Internet Engineering Task Force (IETF). In this way, geospacial location information is associated with Internet based XML content using a standard PIDF-LO format.

Claims

1-30. -30. (canceled)

31. A method of associating Multimedia Internet Message Extensions (MIME) content to a geographic location, comprising:

receiving at a physical presence server, from a physical content proxy server, a universal resource locator (URL) of MIME content;

transmitting, from said physical presence server to a physical GIS server, a latitude/longitude (lat/lon) associated with said MIME content;

receiving back in response from said physical GIS server a first polygon ID associated with said lat/lon of said MIME content;

receiving, at said physical GIS server, a current location of a given wireless device;

transmitting, from said physical GIS server to a physical application server, a second polygon ID associated with said current location of said given wireless device;

receiving, from said physical application server, a request message for identification of MIME content having presence in said second polygon ID;

inserting, at said physical application server, said URL of said MIME content relevant to said second polygon ID into a Presence Information Data Format-Location Object (PIDF-LO) file that lacks geospatial location information identifying a specific physical zone.

32. The method of associating Multimedia Internet Message Extensions (MIME) content to a geographic location according to claim 31, wherein:

said URL of said MIME content is inserted in an “

entity=”

list in a <

presence . . . >

section of said PIDF-LO file.

33. The method of associating Multimedia Internet Message Extensions (MIME) content to a geographic location according to claim 32, wherein:

said URL of said MIME content is also inserted in a “

src=”

list in said <

presence . . . >

section of said PIDF-LO file.

34. The method of associating Multimedia Internet Message Extensions (MIME) content to a geographic location according to claim 31, wherein:

said URL of said MIME content is inserted in a “

name=”

list in a <

presence . . . >

section of said PIDF-LO file.

35. The method of associating Multimedia Internet Message Extensions (MIME) content to a geographic location according to claim 31, wherein:

said geospatial location information is defined using a coordinate based polygon system.

36. The method of associating Multimedia Internet Message Extensions (MIME) content to a geographic location according to claim 35, wherein:

said coordinate based polygon system is defined using an assigned numbering system.

37. The method of associating Multimedia Internet Message Extensions (MIME) content to a geographic location according to claim 31, wherein:

said geospatial location information identifies a specific latitude/longitude.

38. The method of associating Multimedia Internet Message Extensions (MIME) content to a geographic location according to claim 31, wherein:

said geospatial location information is defined directionally.

39. The method of associating Multimedia Internet Message Extensions (MIME) content to a geographic location according to claim 31, wherein:

said MIME content comprises text.

40. The method of associating Multimedia Internet Message Extensions (MIME) content to a geographic location according to claim 31, wherein:

said MIME content comprises images.

41. The method of associating Multimedia Internet Message Extensions (MIME) content to a geographic location according to claim 31, wherein:

said MIME content comprises audio.

42. The method of associating Multimedia Internet Message Extensions (MIME) content to a geographic location according to claim 31, wherein:

said MIME content comprises video.

43. The method of associating Multimedia Internet Message Extensions (MIME) content to a geographic location according to claim 31, wherein:

said MIME content is Multimedia Internet Message Extensions (MIME) type content.

44. The method of associating Multimedia Internet Message Extensions (MIME) content to a geographic location according to claim 31, further comprising:

tagging descriptive information relating to location aware XML content in a <

presence . . . >

section of said PIDF-LO file.

45. The method of associating Multimedia Internet Message Extensions (MIME) content to a geographic location according to claim 44, wherein:

said tagged descriptive information is included in said <

presence . . . >

section of said PIDF-LO file.

46. The method of associating Multimedia Internet Message Extensions (MIME) content to a geographic location according to claim 44, wherein:

said tagged descriptive information includes at least one of;

“

weather”

, “

century”

, “

season”

, and “

year”

tags.

47. The method of associating Multimedia Internet Message Extensions (MIME) content to a geographic location according to claim 44, wherein:

said tagged descriptive information includes at least one of;

“

Time Reference”

, “

Weather Reference”

, and “

Descriptive Reference”

tags.

48. The method of associating Multimedia Internet Message Extensions (MIME) content to a geographic location according to claim 31, wherein:

said URL of said MIME content inserted into said PIDF-LO file is additionally relevant to a user profile associated with said given wireless device.

49. A method of associating XML content to a geographic location, comprising:

receiving at a physical presence server, from a physical content proxy server, a universal resource locator (URL) of Extensible Markup Language (XML) content;

transmitting, from said physical presence server to a physical GIS server, a latitude/longitude (lat/lon) associated with said XML content;

receiving back in response from said physical GIS server a first polygon ID associated with said lat/lon of said XML content;

receiving, at said physical GIS server, a current location of a given wireless device;

transmitting, from said physical GIS server to a physical application server, a second polygon ID associated with said current location of said given wireless device;

receiving, from said physical application server, a request message for identification of MIME content having presence in said second polygon ID;

inserting, at said physical application server, said URL of said XML content relevant to said second polygon ID into a Presence Information Data Format-Location Object (PIDF-LO) file that lacks geospatial location information identifying a specific physical zone.

50. The method of associating XML content to a geographic location according to claim 49, wherein:

said URL of said XML content is inserted in an “

entity=”

list in a <

presence . . . >

section of said PIDF-LO file.

51. The method of associating XML content to a geographic location according to claim 50, wherein:

said URL of said XML content is also inserted in a “

src=”
